To reduce complexity, solve tolerance problems and increase reliability and customer satisfaction, a door switch arrangement for a lavatory of an aircraft is provided, wherein, to generate signals which indicate a current status of the lavatory door, the door switch arrangement uses a sensor device with contactlessly operating reed sensors.

A mounting assembly (10) for the electromagnet (12) of an electromagnetic door locking system, the mounting assembly (10) comprising: a main body portion (14) affixable, in use, to a door frame (18), the main body portion (14) comprising at least two channels adapted to receive a corresponding set of tabs associated with the electromagnet (12) and a set of locking screws (30) cooperating with the channels and being adapted, upon tightening, to deform the channels to clamp the tabs to fix the electromagnet (12) relative to the main body portion (14).

A low-voltage, direct current apparatus for controlling a door, gate, or other access point to a structure or enclosed area. In some embodiments, the apparatus may comprise a housing, a face plate coupled to the housing, a strike plate coupled to the housing, and a keeper disposed between the face plate and the strike plate. The keeper may be rotatably coupled to the housing and may have a cavity configured to receive a latch coupled to a door or other access point. A motor may be disposed within the housing, and a shaft may be coupled to the motor. An actuator arm may be coupled to the shaft. The motor may be operable to rotate the shaft to move the actuator arm from a locked position to prevent movement of the keeper to an unlocked position to allow movement of the keeper.

A modular surface mounted electric strike system is provided. The system comprises a universal base plate having first and second sides, each having first and second mounting points. Each electric strike module includes a header, a keeper assembly, and an actuator assembly configured for moving between a keeper blocking mode and a second mode. When the first and second latches are separated a first distance, the first and second electric strike modules are attached to the first mounting locations on the respective first and second sides of the base plate. When the first and second latches are separated a second distance, the first electric strike module is attached to the second mounting location on either the first or second sides of the base plate, and the second electric strike module is attached to the second mounting location on the other of the first or second side of the base plate.

An exemplary electric strike includes a housing and a keeper pivotally mounted in the housing. The strike also includes a plunger having an extended position and a retracted position, a cage including an aperture, and a locking element movably seated in the aperture. The locking element is engaged with the plunger, and the plunger is structured to urge the locking element radially outward as the plunger moves from an extended position toward a retracted position. The strike also includes a sleeve, a transmission engaged with the sleeve, and a motor drivingly coupled to the transmission. The sleeve is structured to selectively prevent radially outward movement of the locking element and retraction of the plunger. The strike also includes at least one of a lost motion connection and an anti-tamper mechanism.

A low-voltage, direct current apparatus for controlling a door, gate, or other access point to a structure or enclosed area. In some embodiments, the apparatus may comprise a housing, a face plate coupled to the housing, a strike plate coupled to the housing, and a keeper disposed between the face plate and the strike plate. The keeper may be rotatably coupled to the housing and may have a cavity configured to receive a latch coupled to a door or other access point. A motor may be disposed within the housing, and a shaft may be coupled to the motor. An actuator arm may be coupled to the shaft. The motor may be operable to rotate the shaft to move the actuator arm from a locked position to prevent movement of the keeper to an unlocked position to allow movement of the keeper.

A modularized electric latch control device includes a mounting seat and a locking cap device pivotably mounted to the mounting seat and pivotable relative to the mounting seat between a closure position and a non-closure position. Optionally mounted to the electric latch control device are a stopper, a closure member, a locking latch restraining frame, a first escutcheon, and a second escutcheon. The electric latch control device is selectively assembled into a first mode (including the first escutcheon), a second mode (including the closure member, the stopper, and the second escutcheon), or a third mode (including the locking latch restraining frame, the stopper, and the second escutcheon) for cooperating with a cylindrical latch device, a first box type latch device, or a second box type latch device.

An electric latch control device includes a mounting member having an engaging end and a locking member pivotably mounted to the mounting member. A positioning member is pivotably connected to the mounting member and is engageable with the engaging end. A restraining member is engageable with and actuatable by a driving device securely mounted to the mounting member. When the restraining member is in a stopping position preventing pivotal movement of the locking member, the locking member is restrained by the restraining member, and a latch of a door lock is restrained in an opening of the electric latch control device. When the restraining member is in a non-stopping position not preventing pivotal movement of the locking member, the locking member is pivotable from a locking position to an unlocking position to thereby permit disengagement of the latch of the door lock from the opening.

The invention relates to an electromagnetic door opener comprising a housing for installing in a door frame, a pivotable cover which can be rotated between an open position and a closed position, and a security device operating counter to a forced rotation of the cover from the closed position into the open position, which comprises a primary security step and a secondary security step. Said door opener is characterized in that the secondary security step comprises a locking element which is supported in a form fit on the base of the housing of the door opener housing.

A wirelessly-controlled jamb-mounted access control system can include an in-jamb housing, a lock body at least partially inside the housing and rotatable about a first axis between locked and unlocked positions. The first axis can extend parallel to the jamb, and the lock body can include inner and outer sidewalls that define a latch cavity configured to receive a latch tongue of a door. The wirelessly-controlled jamb-mounted access control system can further include an actuator configured to control release of the lock body from the locked position in response to a control signal.
